Look for transfers after ledger + api trans load

If we don't have a pos table built out already (in mem) we can't figure
out the likely dst asset (since there's no pair entry to guide us) that
we should use to search for withdrawal transactions; so move it later.

Further this ports to the new api changes in `piker.pp`` that will land
with #365.
